I suspect that for healthcare providers, the ID requirement is driven more by insurance fraud prevention (including Medicare/Medicaid); i.e. the insurers require the providers to perform due diligence to ensure that the patient being treated is the patient who is covered. I don't know of any examples, but perhaps a provider who did not take insurance would be able to avoid the requirement.
